2- Claims.

This invention relates to ways and means, of a novel and improved character, whereby slick fragile windings of rayoneyarn on a hosiery knittingmachine cone are protected by said means against sticking, undue chafing, and consequent destructive wear.

An object of the invention is toprovide simple, practical and economical structural means which lends itself to satisfactory and accommodating use in association with the usual type cone post and basal portion of the cone, which fits on said post.

In carrying out a preferred embodiment oiv the invention, I provide a readily applicable and removable device employing a centrally apertured wooden disc and a complemental elastic pad atop the wooden disc, thus providing a feasible and serviceable discoidal base for the yarn wound cone.

Further novelty is predicated on the above described base, the central portion of said elastic disc having a compressible depression for the base of the cone.

More particularly, the invention has to do with appreciable refinements and structural distinctions found in an acceptable device which is applicable to the cone spindle, the same being in the form of an appropriate base of laminated form, that is, the base proper being a wooden or equivalent rigid disc which is centrally apertured to fit on the post and the pad being a centrally apertured rubber or equivalent compressibly resilient disc carried by the wooden disc and, as stated, having the aforementioned central portion provided with a depression functioning as a self-adjusting keeper seat for the base of the cone.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings: I Figure 1 is a perspective view of a base constructed in accordance with the principles of the present invention showing, in dotted lines, the manner in which same is adapted to function in association with the spool of yarn and associated cone accommodating post or spindle;

Figure 2 is an enlarged section, fragmentary in character, taken on the plane of the line 22 of Figure 1, looking in. the direction of the arrows.

Referring now to the drawings by distinguishing reference numerals and lead lines, the base as a unitary structure, is denoted by the numeral 5 and is sufficiently rigid to maintain the desired shape and durability and is also sufficiently elas- 2, tie to provide the desired wear-resisting and cush-. ioningproperties wanted. More specifically, the base comprises, as previously noted, a rigid base member which is here shown in the form of a Wooden or equivalent disc 6, the same being contral'lyapertured as at l to accommodate the ver tical spindle or post 8. The cone which carries the yarn 9 is denoted by the numeral l0 and this has its basal or bottom portion I l seating correctly in a central recess l2 provided in the centrally apertured portion of the discoidal cushioning pad l3. The pad is of appropriate thickness and of requisite elasticity and is preferably constructed of foam rubber and has its bottom surface glued or otherwise secured, as at M, to the top of the wooden or equivalent base plate 6. Thus, the lower portion of the cone is seated in the recess I2 and the lower windings or strands of the yarn come into resting contact with the pad I3. The face of the pad on which the yarn rests is thus appropriate to protect the yarn and to avoid, under ordinary circumstances, breakage of the yarn. In practice, the pad is approximately seven inches in diameter and has onequarter of an inch hole through its center which fits properly on the yarn post. The recess is approximately one-quarter of an inch deep and two and one-eighth inches in diameter to provide an appropriate central seat for the yarn cone. The outside wall of the pad is approximately one inch thick and the pressed wood base or disc is one-eighth of an inch thick and seven inches in diameter.

In all, the invention constitutes a simple, practical and eiiective basing means characterized by requisite facilities affording effective and appropriate protection for the yarn, whereby to prevent undue wear and tear and breakage of the yarn windings.

It is a matter of common knowledge that many and varied styles of basing devices have been employed on and in connection with hosiery knitting machines. Due to the fine quality and slick characteristics of rayon-yarn the factor of material embodied in the basing device is indeed significant. Trial and error procedures have involved the use of both wooden and felt pads and many have tried using a so-called tin pie pan to assist in winding and unreeling with the least possibility of the windings hanging and breaking, The material felt has, it seems, an affinity for lint and ravelings and if and when the active surface of the pad becomes choked with lint deposits, the yarn windings are more susceptible to adhesion and breakage. Foam rubber as herein mentioned seems possessed of the desired characteristics of compressibility, resiliency, lightness in weight and an unusually smooth and fiat finish and yarn does not stick to same. Consequently, foam rubber is referred to in this field as substantially lint proof. Then, too, the diameter of the depression conforms to the greatest outside diameter of the cone, which is at the base of the cone, and the base of the cone seats itself in the depression in an obvious manner. The weight of a cone of yarn is, generally speaking, about three pounds. This weight diminishes as the yarn unwinds and as the weight reduces, the elevation of the cone rises and permits the unwindings to run free and here again the factor of friction and breakage may be coped with to greatest advantage.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

Having described the claimed as new is:

1. A rayon-yarn protector for use on a hosiery knitting machine comprising a horizontally disposable discoidal rigid base centrally apertured and adapted to be mounted on a vertical cone supporting post, and a centrally apertured discoidal pad superimposed on and fastened to the invention, what is top surface of said base, said pad being of a diameter corresponding to the diameter of the base, being compressibly resilient, the upper yarn receptive surface of said pad being smooth and flat, and the center of said upper surface having a relatively shallow concentric depression, the outside diameter of said depression corresponding to the greatest diameter of the cone which is seatable in said depression, the portion of the pad ranging from the outer peripheral edge of the pad to the outer peripheral edge of the depression being of uniform thickness.

2. The structure specified in claim 1 wherein said pad is made of foam rubber.
